Borland’s JBuilder-on-Eclipse emerges

Borland CodeGear has announced details of JBuilder 2007, the first version of its Java IDE to be built on the Eclipse platform.

I’ve read quickly through the various PDFs, but it is hard to get a feel for the product from these alone. Is it more like Eclipse, or more like JBuilder 2006? What has happened to the Swing designer, which was the best in the business until Matisse came along. What must-have features is CodeGear providing to tempt developers away from NetBeans or plain old Eclipse?
